METHOD OF UNITING TEX TILE STRANDS.

Specification of Letters Patent.

Application filed March 21, 1916. Serial No. 85,552.

To all whom it may concern:

Be it known that we, EMORY J. LII-rs and LLOYD Ha LIPPS, citizens of the United States, residing at Fountain Hill borough, in the countyof Lehigh and State of Pennsylvania, have invented certain new and useful Improvements in Methods of Uniting Textile Strands, of which the following is a specification.

In doubling and twisting threads and the like, after each thread has been subjected to what is known as a first-time twist and 'wound on its individual bobbin the two threads are transferred to a common bobbin.

Theyare then subjected to a second time twist, accomplished by rotating the latter bobbin on its own axis as the threads are drawn therefrom substantially longitudinally of said axis. Since the threads as de posited on the second bobbin are not in any way united with each other, as by being twisted about each other, but lie simply side by side, it is necessary in the second time operation to employ a flier or equivalent to keep them together; because of the abrasive action of this device on the threads the draft speed in the second time operationis necessarily limited, and at thebest the operation is attended with frequent breakage of the threads, involving annoying and timewasting interruptions. To overcome this it has been proposed to introduce a preliminary twisting operation before the threads are subjected to the second time twist,

such preliminary twisting operation involving a twist of relatively long pitch designed simply to hold the two threads united or together, and thus make unnecessary the use of a flier or the like-abr'ading medium, during the second-time twisting operation.

The means for accomplishing this so-called preliminary second-time twist is complicated and of a character requiring special skill to control it and preserve it in proper working order, and its use obviously involves an operation performed wholly apart from any other operation on the material.

The object of this invention is to make the use of fliers unnecessary and in a simple way, by a treatment performed simultaneously with the doubling operation, to connect the threads with each other so that they will be adapted to undergo the second-time twisting or spinning operation, z. 6., in their doubled state be bound together, as in this secondtime operation they are drawn from the rotating wound package into which they have been formed. This we have in practice accomplished by causing the wrapping of one or each) of the strands around the other alternately right and left by drawing the strands lengthwise over a suitable surface and simultaneously effecting back and forth movement as between said surface and the strands crosswise. of the line of draft and forming the strands, thus consequently and while so bound together, into a wound package.

It is not indispensable that the right and left wrapping take place simultaneously with the doubling, as the doubling may in some instance have been already performed. Nor is it indispensable that the wrapping be effected by drawing the threads over a ed, that the wrapped strands be formed into a wound package. Nor is it indispensable, though it will usually be the case, that the strands be drawn lengthwise while the wrapping is proceeding, the bro'ad idea in this aspect of our invention being the right and left wrapping of one strand around the other and forming the strands, as bound together by the wrapping, into a wound package.

In the annexed drawings, Figure 1 is a fragmentary front elevation of one form of a machine suitable for performing the invention; Fig. 2 is a vertical sectional view of what is shown in Fig. 1; Fig. 3 is a plan view, showing parts not appearing in Fig. 1; and, Fig.4 is a view illustrating diagrammatically the alternate right and left wrapping of either strand around the other.

a is the frame of the machine, being a doubling machine of well-known type; b the rail on which is supported the pair of spools c on which the strands with the first time twist are wound; (Z is the spool on which is wound the material formedvin accordance with this invention, the same being suitably journaled in the frame; ,6 is a traverse rail having a guide 7 and arranged to reciprocate the frame transversely of the line of draft of the material; 9 is a wheel for rotating the spool d, the same being arranged on a shaft h journaled in the frame; and 2' the mechanism for "rotating v the shaft h and reciprocating the traverse rail.

-to be described herein.

Suitably supported more or less near the spool 03 in brackets Z projecting from the frame of the machine is a bar m which ispreferably cylindrical in cross section and is arranged to I reciprocate in said brackets.

The said bar in the'present adaptation is reciprocated-v from the traverse rail through the medium ofpinions n and 0 which rotate as one and may be'journaled on a bracket p projecting from the frame, respectively meshing with rack teeth n and 0 formed on the traverse rail and bar m. The strands extend over the bar m and traverse rail to the spool d.- Thebar m, as it reciprocates,

preferably presents a longitudinally smooth surface to the strands. The throw of the bar m is somewhat greater than thatof the traverse rail.

9 is a special guide for the strands pro-- jec'ting from rail 0 below bar m, being set preferably obliquely in the present instance (but it may be otherwise formed or adapted) tokeep the strands close together and preferably in actual contact with each other and thus insure their wrapping around each other,..as they will not do if separated at this point. 1

' In the operation of the mechanism specifically shown,- the means 2' while causing the spool 03 to rotate also causes the traverse rail and ba'r mto reciprocate'in opposite directions, thus, while the traverse rail lays the doubled material on the'spool din coils progressing back and forth from one to the other end of the spool, thecoaction of said' "traverse railvand'bar m, because one moves 'relativelytin this case, oppositely) to the other, results in each strand being rolled and thus wrapped around the other in coils progressing alternately to right and left as diagrammatically shown in Fig. 4. This figure is intended to illustrate'simply the reverse, or alternately right and left, wrap ping of the coils, only one of the strands being'here shown as afiecte'd by the wrap ping action andwhile we do-not wish-to 5 exclude sucha wrapping/of coils as wouldaffect but one of the strands, still in actual practice itwill usually be found that each of the strands will receive a wrapping action around the other. i p

s In the present instance, as fast as the wrapping proceeds the wrapped portion of the strands is wound up in a package on the spool 11 so that the wrappedcondition is re tained in the material as an incident to its being Wound, more or less tightly, on said spool, and further remains therein for the purpose and with the effect in actual practice of keeping the strands bound together 1 as in the spinning operation the material is drawn from the spool d ontoa receiving spool or bobbin.

Having thus fully described our inven-' tion, what we claim as new and desire to .secure by Letters Patent is 1. The 'hereindescribed method of uniting textile strands which consists in drawing the strands lengthwise and simultaneously wrapping one strand around the other alternately right and left'and forming the strands as thus wrapped into a wound package.

2. The hereindescribed method of uniting textile strands which consists in drawing the strands lengthwise over a suitable surface and simultaneously effecting relative back and forth movement as between said surface and the strands crosswise of "theline of draft, whereby to wrap one strand around .the other alternately right and left- 3; Thehereindescribed method of uniting textile strands which consists inwrapping one strand alternately rightand left around the other and forming the strands as thus wrapped into a wound package.
